I don't think so....
I don't think it is an interview for your asylum. Why would they want to interview you for the status you already have been granted? Plus, if they want to revoke your asylum, I think that it had to be done by IJ.
As most of us are aware of the fact that 2% of asylum based adjustment cases are "randomly" picked for the interview for quality control purposes. Usually these interviews are a mere formality.
Please don't worry too much, if you haven't done anything criminal, then I'd advise you to go to your interview with your chin up and tackle it with confidence.
Even if the situation in your home country have changed it has not been a practice of USCIS to start revoking the asylum status of people from that region. Come on! for example, how many people from Afghanistan do we know who had their status revoked just because the situation has changed in that country? Or Bosnia or Veitnam and list goes on.
So just take it easy, you'll be just fine. Let's know when is your interview and keep us all posted.
